In v1.6, we have added a global channel name setting as well among with other settings (hook url was there already). However, we wanted the channel name and hook url behave the same, e.g.: if local hook url overrides the global one (that is, it is non-empty), it should not matter that the override flag is enabled, it should use the local settings. This was behaving incorrectly with the channel name setting in v1.6, now we fixed that.

Add global configuration for notifications (#15): Now you have the ability to configure all options globally, and override them locally, if you wish. There is a new flag locally that turns on the override option. Also note that it is not required to enable the flag if you just want to override the channel name or hook url. However, you HAVE to edit the channel name if you enable the override flag (for hook url, this is still not needed).

Verbose, Compact and Minimal notification levels for pull requests as well (#16)

Ability posting to multiple Slack channels: use a comma separated list of channels names in this case (#8)

Ability to control the granularity of the pull request activity (#10). NOTE: Existing instances will have ALL pull request events disabled when you upgrade, unless you enable some or all events again in the repo settings config page. This is because existing instances don't currently have the filter checkboxes prior 1.4, so all events will be ignored unless you go to the config and set them.
